This clinical trial studies glycoprotein and glycan in tissue and blood samples of patients with stage IB-IVA cervical cancer undergoing surgery to remove pelvic and abdominal lymph nodes. Studying samples of tumor tissue and blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors learn how far the disease has spread.

Primary and metastatic tumor specimens are collected during lymphadenectomy and used for tissue microarray analysis, mutational analysis of T-synthase and Cosmc, immunohistochemical staining of Tn antigen and sialyl Tn antigen, and customized gene expression array analysis of 400 genes associated with glycobiology. Pre-lymphadenectomy blood is collected from patients at baseline for customized glycan array analysis of 300 carbohydrates.

Procedure: Lymphadenectomy

Undergo lymphadenectomy

Other Names:

excision of the lymph node

Lymph Node Dissection

lymph node excision

Detailed Description:

PRIMARY OBJECTIVE:

I. Determine whether the presence of a mutation in T-synthase or Cosmc and/or the presence of positive immunohistochemical expression of Tn antigen or sialyl Tn antigen in tumor specimens is associated with progression-free or overall survival in patients with stage IB2, II, III, or IVA cervical cancer undergoing pelvic and para-aortic (abdominal) lymphadenectomy.

SECONDARY OBJECTIVES:

I. Determine whether the presence of a mutation in T-synthase or Cosmc and/or the presence of positive immunohistochemical expression of Tn antigen or sialyl Tn antigen in tumor specimens is associated with lymph node metastasis or local control.

II. Identify a glycoprotein profile from a customized gene expression array analysis in tumor specimens or a glycan profile from a customized glycan array in serum that is associated with lymph node metastasis, local control, disease recurrence/progression, or survival.

IV. Identify differences in glycoprotein expression profiling and glycan profiling in tumor specimens with or without a mutation in T-synthase or Cosmc, or in tumor specimens with or without positive immunohistochemical expression of Tn antigen or sialyl Tn antigen that are associated with lymph node metastasis, local control, disease recurrence/progression, or survival.

OUTLINE:

Primary and metastatic tumor specimens are collected during lymphadenectomy and used for tissue microarray analysis, mutational analysis of T-synthase and Cosmc, immunohistochemical staining of Tn antigen and sialyl Tn antigen, and customized gene expression array analysis of 400 genes associated with glycobiology. Pre-lymphadenectomy blood is collected from patients at baseline for customized glycan array analysis of 300 carbohydrates.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Patients with a block or 25 unstained sections of formalin-fixed and paraffin-embedded primary tumor available to satisfy the primary tumor requirement
